File-level commenting

ABSTRACT

Various embodiments provide a commenting system for multiple users to provide and share comments to shared content items. For example, users can share a web link to a collection of content items, such as documents, spreadsheets, photos, and any other media, with other users stored in an online content management system. To enable such functionality, the online content management system can expose an application programming interface to enable third-party service providers to develop and attach a comment interface to content items. Accordingly, such a commenting system can provide a comment interface for concurrent display alongside a respective content item in which users can provide comments to shared content items or to use as notes for their personal content items.

TECHNICAL FIELD

The present technology pertains to editing shared content items, and more specifically pertains to enabling users viewing and/or editing shared content items to provide shared comments for other users to view.

BACKGROUND

Various applications allow users to view and/or edit the same file or content. In order to add comments or view changes to a document, however, users have been limited to embedding comments in the text of the document or by using a commenting or versioning feature of the native application used to create the file. Furthermore, if the user only has read access to the document, the user will have to download a copy of the file, add their respective comments and send it back to the owner, or send the owner comments through some other mechanism, such as email.

SUMMARY

Additional features and advantages of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or can be learned by practice of the herein disclosed principles. The features and advantages of the disclosure can be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the disclosure will become more fully apparent from the following description and appended claims, or can be learned by the practice of the principles set forth herein.

Disclosed are systems, methods, and non-transitory computer-readable storage media for providing a comment interface to enable users to add comments to content items. For example, a content item, such as a document or image, can be shared, viewed, and/or edited, by multiple users, each of whom can provide comments to a commenting interface to share their comments or thoughts with the other users.

A content management system, in accordance with various embodiments, can make a content item available for retrieval by providing the content item for display on, for example, a first computing device of a user through a network. The content item can include a comment interface displayable therewith, which can be viewable between the first computing device and at least one second computing device through an account with the content management system. Accordingly, the user can provide comments to the comment interface that can be viewed on both the first computing device and the second computing device. Further, the content item can be shared among other users through the online content management system and each user can provide comments to the comment interface to share their thoughts and comments with other users viewing and/or editing the content item.

In one example, the comment interface can be provided through an application, plug-in, or any other interface, associated with the content management system or other third party application other than the native application of the content item. Accordingly, the comment interface being unassociated with the native application of the content item enables comments to be attached to a content item in a manner that does not alter the data in the content item itself. This can enable commenting on content items that are shared between users using different sharing models (e.g., read-only, read-write, etc.)

Further comments can be provided to a content item via metadata. In one example, the online content management system can expose metadata or some other functionality to third party developers through an Application Programming Interface (API). Accordingly, the third party developers, using the API, can attach a comment, a comment interface for the content item, or some other information to a content item, without modifying the raw file data.

The comments can be displayed in a variety of ways, such as in a comment interface alongside the content of the document. In some cases, the comments can scroll independently of the content in the document. Alternatively, the comments can be linked to a location in a document and the scrolling of the comments can be linked to the scrolling of the document such that corresponding comments are displayed. Further, the comments can be selectively displayable such that the user can choose whether to display the comment interface concurrently with the content item or whether to display the content item without the comment interface.

DESCRIPTION

Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the art will recognize that other components and configurations may be used without departing from the spirit and scope of the disclosure.

The disclosed technology addresses the need in the art for enabling users to provide information, such as comments, metadata, or the like, to content items viewable by multiples users across multiple computing device, platform, and file types. In particular, users can provide comments to a comment interface associated with a content item, such as a document or image, which is available for viewing and/or editing through an online content management system. In one example, the comment interface can be provided through an application, plug-in, or other interface, associated with the content management system and, in some instances, unassociated with the native application of the content item.

Further comments can be provided to a content item via metadata. In one example, the online content management system can expose metadata or some other functionality to third party developers through an Application Programming Interface (API). As used herein, an API is a set of programming instructions and standards for accessing Web-based software applications or tools. The online content management system, in this example, can release an API to the public so that software developers can design products that are powered by services provided by the online content management system. Accordingly, the third party developers, using the API, can attach a comment, a comment interface for the content item, or some other information or application to a content item, without modifying the raw file data.

FIG. 1 shows example document 100 displayed on browser 102, in accordance with at least one embodiment. In various embodiments, document 100 is one of many content items or files available for retrieval from an online content management system that can offer services, such as cloud storage, file synchronization, and various other types of client software. For example, such a system may allow users to create a folder on each of their computing devices, such as their smartphone, tablet computer, desktop computer, laptop, and the like. The folder can be synchronized across all the devices so that the content of the folder, when changed or updated, appears the same when viewed across all devices, regardless of the device or platform type. Files placed in such a folder can be accessible through a website or mobile application associated with one or more of the devices and can also be shared with the devices of other users.

In accordance with at least one embodiment, the online content management system can expose functionality for enabling users to provide comments to content items. In one example a user can choose to provide comments to document 100 by selecting icon 104, which, in one example, will expand comment interface or section 106. In this example, comment section 106 can be an application provided by a third-party service provider that communicates or interfaces with the content item through metadata or an API provided by the online content management system. Accordingly, comment section 106 includes, in this example, text field 108 for a user to provide their comment, a share icon 110 to share document 100 with other users, and settings icon 112 for changing user and account preferences.

In at least one embodiment, a user can provide one or more comments to text field 108 after, for example, editing document 100 and sharing the document with other users. Accordingly, document 100, in this example, has been shared with and viewed by other users. In this example, there are three users and each has provided comments to an initial question posed by a first user at the top of section 106. In this example, the first user has created document 100, shared document 100 with a second and third user, asked the second and third user for their feedback, and the second and third user have provided their thoughts in section 106.

In one example, each user could have provided edits to document 100 and explanations for their edits. In one example, each of the comments could be linked to a specific location in the document, such as to reword or add content to a specific paragraph. Alternatively, the comments could be general and about the document as a whole, such as about the background color of document 100. Further, both linked comments and general comments could simultaneously be provided to comment section 106. For example, comments to a specific location or section could be linked to the specific location in document 100, such that when a user selects a respective comment, they are brought to the location in document 100 associated with the respective comment. Accordingly, the general comments, when selected, would not navigate the user to a location since they are not associated with any particular location.

Accordingly, after each user has provided their comments, which are received through the API, the file associated with document 100 can be synchronized across each of the user's computing devices in order for each user to have access to a most recent version of document 100, including the most recent comments from all shared users. The synchronization can be performed as a “push,” when a respective user saves or closes document 100, thereby pushing the most recent version to each device associated with the users or as a “pull,” when a respective user requests access to document 100 in order to ensure that changes to document 100 and/or comment section 106 are reflected across all associated computing devices.

Further, local peer-to-peer synchronization could also be utilized within the scope of various embodiments discussed herein. For example, devices associated with the same user or having access to the same shared folder can determine whether they are on the same local area network, and if so establish a secure connection (e.g., via SSL) and effect synchronization through peer-to-peer transfer of files. The synchronized files may, typically, only be provided to computing devices associated with a user who provided the files. For example, if a particular user registers his tablet computer, laptop, and smartphone with the content management system, then those three devices will synchronize the files with those devices and otherwise make the file available to the user via the user's login (e.g., via a web-based or app-based interface). Accordingly, the content management system will not by default make the files available to devices of other users or via logins other than that of the user who provided the files.

As discussed elsewhere herein, comment section 106 can be provided across devices, platforms, and file types. For example, the content management system can provide storage, retrieval, editing, and commenting service for content items such as word processing documents, spreadsheets, presentations, videos, streaming content, images, and any other content or file type. Accordingly, FIG. 2 shows image 200 displayed on browser 202, in accordance with at least one embodiment. In this example, image 200 could be part of a photo album shared among a user's friends and family, therefore, the user's friends and family could provide comments by typing a message in text field 208 of comment section 206 to be shared among the shared users, as described above with respect to FIG. 1. Additionally, the user could upload image 200 for private storage and safekeeping with the online content management system and provide comments to comment section 206 to jot down notes about particular memories, places, and the like, associated with image 200 or to a particular album in general.

In at least one embodiment, the comment section is provided on an interface different from a native application associated with a respective content item. For example, the comment section could be an application layer independent from, or layered on top of, the native application of a respective file type being displayed. In one example, the layer could be associated with an application provided by the third-party service provider or by a browser plug-in associated with the third-party service provider when viewed through a web browser. In one example, this could be achieved by adding metadata to each content item that is readable by the application provided or the metadata could point to a location with comment data that is retrievable, from the third-party service provider, by the online content management system.

Accordingly, a second type of comment can be created by a user. For example, a user could pick a location in a file, such as a document, image, or presentation, for a comment and then add text to that particular location. For example, in file “commenting screenshot 1” a single comment could be attached to a respective slide (of the document, image, or presentation) at a point labeled A, along with the corresponding comment displayed in the comments section. A comment can also identify a particular user that left the comment along with the date and time the comment was provided.

FIG. 3 shows example environment 300 in which various embodiments can be implemented. In this example, online content management system 302 can store and make content items (304 a, 304 b, 304 c, 304 d) available for retrieval by providing the content items for display on first computing device 312 and second computing device 316 upon request through a network. In this example, online content management system 302 provides or exposes API 306 to enable third-party service provider or developer 308 to attach/provide information or additional functionality to content items (304 a, 304 b, 304 c, 304 d) that may not be available through a native application associated with one of content items (304 a, 304 b, 304 c, 304 d).

For example, developer 308 can develop a comment interface, such as discussed elsewhere herein, that enables user 310 and/or user 314 to provide comments to or alongside content items (304 a, 304 b, 304 c, 304 d). In this example, the comment interface communicates or interfaces with content items (304 a, 304 b, 304 c, 304 d) through API 306 and, since the comment interface is a layer on top of the native application associated with a respective content item (304 a, 304 b, 304 c, 304 d), a comment can be provided to the comment interface without modifying the raw file data of the respective content item (304 a, 304 b, 304 c, 304 d).

Accordingly, in this example, both user 310 and user 314 could each (or at least user 310) have an account with online content management system 302, which enables both users to upload a content item, such as content item (304 a, 304 b, 304 c, 304 d), for storage and retrieval. In this example, content item 304 b could be a collaborative word processing document, as discussed with respect to FIG. 1, which user 310 had originally uploaded through computing device 312. In this example, user 310, utilizing a comment interface provided by developer 308, could insert one or more comments, for example, posing questions or explaining portions of content item 304 b to his coworkers (user 314) to whom content item 304 b will eventually be presented to for feedback. In one example, the comment(s) are received through the comment interface and data for each comment is stored with online content management system 302 or, alternatively, the comments can be stored with developer 308 and data pointing to a location of a respective comment stored with developer 308 can be stored with online content management system 302.

Accordingly, user 310 can share content item 304 b with user 314 by sending an invitation in the form of, for example, a link to content item 304 b available through an account associated with user 310. User 314, after accepting the invitation, can view content item 304 b on computing device 316 (or another device) and provide one or more comments to the comment interface. After user 314 provides their comment(s), online content management system 302 synchronizes the provided comment(s) and any changes made to content item 304 b via second computing device 316 (or another device) with a copy of content item 304 b stored with online content management system 302 and/or a copy stored locally on computing device 312 (and any other devices associated therewith). Accordingly, user 310, after the synchronization is performed, can view the comment(s) provided by user 314 by accessing content item 304 b though computing device 312.

FIG. 4 shows example environment 400 in which various other embodiments can be implemented. In this example, online content management system 410, as discussed above, can store and make content items (406 a, 406 b, 406 c) available for retrieval by providing the same for display on first computing device 404 and second computing device 414 upon request through a network. In this example, online content management system 410 exposes API 412 to enable third-party service provider 408 to utilize or otherwise interface with content items (406 a, 406 b, 406 c) in order to provide additional services that may not be available through a native application associated with one of content items (406 a, 406 b, 406 c).

In this example, third-party service provider 408 could be a social network or file sharing application or website for which online content management system 410 exposes API 412 to enable user 414 to automatically share images, such as discussed with respect to FIG. 2 for example, that are uploaded to an album stored with online content management system 410. In one example, content item 406 a could be an image and user 414 could share the same with user 402 by uploading the image to online content management system 410 via computing device 416, which is subsequently made available through third-party service provider 408. In this example, user 402 via computing device 404 could, for example, edit the image by applying filters, inserting text, drawing on the image using a paint feature, or the user could comment on the image and the like.

Accordingly, after user 402 edits and/or comments on the image (content item 406 a), online content management system 410 can synchronize the same with a copy of content item 406 a stored with online content management system 410 and/or a copy stored locally on computing device 416. Accordingly, user 414, after the synchronization is performed, can view the edits and/or comments provided by user 402 by accessing content item 406 b though computing device 416.

FIG. 5 shows an example process 500 for enabling users to provide comments to shared documents through a content management system in accordance with various embodiments. It should be understood that, for any process discussed herein, there can be additional, fewer, or alternative steps performed in similar or alternative orders, or in parallel, within the scope of the various embodiments unless otherwise stated.

In this example, a content item uploaded to an account of an online content management system is received 502. The content item, in this example, can be a word processing document, a spreadsheet, a presentation file, a video, streaming content, an image, and the like digital content. The online content management system, in this example, exposes metadata of the content item to third-parties to provide a comment section for users to insert comments associated with the content item 504. In one example, the metadata is made available to third parties through an API, which can be different or the same for various applications associated with a respective content item. In this example, the content item is provided for display on a first computing device 506. Accordingly, a comment is received from a user of the first computing device to the comment section provided by the third party 508. Upon identifying a change to the content item or upon receiving a comment, the content item is synchronized with a copy of the content item stored with the online content management system and/or a second computing device 510. Accordingly, the content item and the comment can be provided for display on the second computing device 512.

An exemplary system configuration 600 for sharing documents and providing synchronized comments among users for the shared documents is shown in FIG. 6, wherein computing devices communicate via a network for purposes of exchanging content and other data. The system can be configured for use on a wide area network such as that illustrated in FIG. 6. However, the present principles are applicable to a wide variety of network configurations that facilitate the intercommunication of electronic devices. For example, each of the components of system 600 in FIG. 6 can be implemented in a localized or distributed fashion in a network.

In system 600, a user can interact with content management system 606 through computing devices 602 ₁, 602 ₂, . . . , 602 _(n) (collectively “602”) connected to network 604 by direct and/or indirect communication. Content management system 606 can support connections from a variety of different computing devices, such as desktop computers; mobile computers; mobile communications devices, e.g. mobile phones, smart phones, tablets; smart televisions; set-top boxes; and/or any other network enabled computing devices. Computing devices 602 can be of varying type, capabilities, operating systems, etc. Furthermore, content management system 606 can concurrently accept connections from and interact with multiple computing devices 602.

A user can interact with content management system 606 via a client-side application installed on computing device 602 _(i). In some embodiments, the client-side application can include a content management system specific component. For example, the component can be a stand-alone application, one or more application plug-ins, and/or a browser extension. However, the user can also interact with content management system 606 via a third-party application, such as a web browser, that resides on computing device 602 _(i) and is configured to communicate with content management system 606. In either case, the client-side application can present a user interface (UI) for the user to interact with content management system 606. For example, the user can interact with the content management system 606 via a client-side application integrated with the file system or via a webpage displayed using a web browser application.

Content management system 606 can make it possible for a user to store content, as well as perform a variety of content management tasks, such as retrieve, modify, browse, and/or share the content. Furthermore, content management system 606 can make it possible for a user to access the content from multiple computing devices 602. For example, computing device 602 _(i) can upload content to content management system 606 via network 604. The content can later be retrieved from content management system 606 using the same computing device 602 _(i) or some other computing device 602 _(j).

To facilitate the various content management services, a user can create an account with content management system 606. The account information can be maintained in user account database 650. User account database 650 can store profile information for registered users. In some cases, the only personal information in the user profile can be a username and/or email address. However, content management system 606 can also be configured to accept additional user information.

User account database 650 can also include account management information, such as account type, e.g. free or paid; usage information, e.g. file edit history; maximum storage space authorized; storage space used; content storage locations; security settings; personal configuration settings; content sharing data; etc. Account management module 624 can be configured to update and/or obtain user account details in user account database 650. The account management module 624 can be configured to interact with any number of other modules in content management system 606.

An account can be used to store content, such as digital data, documents, text files, audio files, video files, etc., from one or more computing devices 602 authorized on the account. The content can also include folders of various types with different behaviors, or other mechanisms of grouping content items together. For example, an account can include a public folder that is accessible to any user. The public folder can be assigned a web-accessible address. A link to the web-accessible address can be used to access the contents of the public folder. In another example, an account can include a photos folder that is intended for photos and that provides specific attributes and actions tailored for photos; an audio folder that provides the ability to play back audio files and perform other audio related actions; or other special purpose folders. An account can also include shared folders or group folders that are linked with and available to multiple user accounts. The permissions for multiple users may be different for a shared folder.

The content can be stored in content storage 660. Content storage 660 can be a storage device, multiple storage devices, or a server. Alternatively, content storage 660 can be a cloud storage provider or network storage accessible via one or more communications networks. Content management system 606 can hide the complexity and details from computing devices 602 so that computing devices 602 do not need to know exactly where the content items are being stored by content management system 606. In one variation, content management system 606 can store the content items in the same folder hierarchy as they appear on computing device 602 _(i). However, content management system 606 can store the content items in its own order, arrangement, or hierarchy. Content management system 606 can store the content items in a network accessible storage (SAN) device, in a redundant array of inexpensive disks (RAID), etc. Content storage 660 can store content items using one or more partition types, such as FAT, FAT32, NTFS, EXT2, EXT3, EXT4, ReiserFS, BTRFS, and so forth.

Content storage 660 can also store metadata describing content items, content item types, and the relationship of content items to various accounts, folders, or groups. The metadata for a content item can be stored as part of the content item or can be stored separately. In one variation, each content item stored in content storage 660 can be assigned a system-wide unique identifier.

Content storage 660 can decrease the amount of storage space required by identifying duplicate files or duplicate segments of files. Instead of storing multiple copies, content storage 660 can store a single copy and then use a pointer or other mechanism to link the duplicates to the single copy. Similarly, content storage 660 can store files more efficiently, as well as provide the ability to undo operations, by using a file version control that tracks changes to files, different versions of files (including diverging version trees), and a change history. The change history can include a set of changes that, when applied to the original file version, produce the changed file version.

Content management system 606 can be configured to support automatic synchronization of content from one or more computing devices 602. The synchronization can be platform agnostic. That is, the content can be synchronized across multiple computing devices 602 of varying type, capabilities, operating systems, etc. For example, computing device 602 _(i) can include client software, which synchronizes, via a synchronization module 632 at content management system 606, content in computing device 602 _(i)'s file system with the content in an associated user account. In some cases, the client software can synchronize any changes to content in a designated folder and its sub-folders, such as new, deleted, modified, copied, or moved files or folders. The client software can be a separate software application, can integrate with an existing content management application in the operating system, or some combination thereof. In one example of client software that integrates with an existing content management application, a user can manipulate content directly in a local folder, while a background process monitors the local folder for changes and synchronizes those changes to content management system 606. Conversely, the background process can identify content that has been updated at content management system 606 and synchronize those changes to the local folder. The client software can provide notifications of synchronization operations, and can provide indications of content statuses directly within the content management application. Sometimes computing device 602 _(i) may not have a network connection available. In this scenario, the client software can monitor the linked folder for file changes and queue those changes for later synchronization to content management system 606 when a network connection is available. Similarly, a user can manually stop or pause synchronization with content management system 606.

A user can also view or manipulate content via a web interface generated and served by user interface module 622. For example, the user can navigate in a web browser to a web address provided by content management system 606. Changes or updates to content in the content storage 660 made through the web interface, such as uploading a new version of a file, can be propagated back to other computing devices 602 associated with the user's account. For example, multiple computing devices 602, each with their own client software, can be associated with a single account and files in the account can be synchronized between each of the multiple computing devices 602.

Content management system 606 can include a communications interface 620 for interfacing with various computing devices 602, and can interact with other content and/or service providers 609 ₁, 609 ₂, . . . , 609 _(n) (collectively “609”) via an Application Programming Interface (API). Certain software applications can access content storage 660 via an API on behalf of a user. For example, a software package, such as an app on a smartphone or tablet computing device, can programmatically make calls directly to content management system 606, when a user provides credentials, to read, write, create, delete, share, or otherwise manipulate content. Similarly, the API can allow users to access all or part of content storage 660 through a web site.

Content management system 606 can also include authenticator module 626, which can verify user credentials, security tokens, API calls, specific computing devices, and so forth, to ensure only authorized clients and users can access files. Further, content management system 606 can include analytics module 634 module that can track and report on aggregate file operations, user actions, network usage, total storage space used, as well as other technology, usage, or business metrics. A privacy and/or security policy can prevent unauthorized access to user data stored with content management system 606.

Content management system 606 can include sharing module 630 for managing sharing content publicly or privately. Sharing content publicly can include making the content item accessible from any computing device in network communication with content management system 606. Sharing content privately can include linking a content item in content storage 660 with two or more user accounts so that each user account has access to the content item. The sharing can be performed in a platform agnostic manner. That is, the content can be shared across multiple computing devices 602 of varying type, capabilities, operating systems, etc. The content can also be shared across varying types of user accounts.

In some embodiments, content management system 606 can include a content item management module 628 for maintaining a content directory. The content directory can identify the location of each content item in content storage 660. The content directory can include a unique content entry for each content item stored in the content storage.

A content entry can include a content path that can be used to identify the location of the content item in a content management system. For example, the content path can include the name of the content item and a folder hierarchy associated with the content item. For example, the content path can include a folder or path of folders in which the content item is placed as well as the name of the content item. Content management system 606 can use the content path to present the content items in the appropriate folder hierarchy.

A content entry can also include a content pointer that identifies the location of the content item in content storage 660. For example, the content pointer can include the exact storage address of the content item in memory. In some embodiments, the content pointer can point to multiple locations, each of which contains a portion of the content item.

In addition to a content path and content pointer, a content entry can also include a user account identifier that identifies the user account that has access to the content item. In some embodiments, multiple user account identifiers can be associated with a single content entry indicating that the content item has shared access by the multiple user accounts.

To share a content item privately, sharing module 630 can be configured to add a user account identifier to the content entry associated with the content item, thus granting the added user account access to the content item. Sharing module 630 can also be configured to remove user account identifiers from a content entry to restrict a user account's access to the content item.

To share content publicly, sharing module 630 can be configured to generate a custom network address, such as a uniform resource locator (URL), which allows any web browser to access the content in content management system 606 without any authentication. To accomplish this, sharing module 630 can be configured to include content identification data in the generated URL, which can later be used to properly identify and return the requested content item. For example, sharing module 630 can be configured to include the user account identifier and the content path in the generated URL. Upon selection of the URL, the content identification data included in the URL can be transmitted to content management system 606 which can use the received content identification data to identify the appropriate content entry and return the content item associated with the content entry.

In addition to generating the URL, sharing module 630 can also be configured to record that a URL to the content item has been created. In some embodiments, the content entry associated with a content item can include a URL flag indicating whether a URL to the content item has been created. For example, the URL flag can be a Boolean value initially set to 0 or false to indicate that a URL to the content item has not been created. Sharing module 630 can be configured to change the value of the flag to 6 or true after generating a URL to the content item.

In some embodiments, sharing module 630 can also be configured to deactivate a generated URL. For example, each content entry can also include a URL active flag indicating whether the content should be returned in response to a request from the generated URL. For example, sharing module 630 can be configured to only return a content item requested by a generated link if the URL active flag is set to 6 or true. Thus, access to a content item for which a URL has been generated can be easily restricted by changing the value of the URL active flag. This allows a user to restrict access to the shared content item without having to move the content item or delete the generated URL. Likewise, sharing module 630 can reactivate the URL by again changing the value of the URL active flag to 6 or true. A user can thus easily restore access to the content item without the need to generate a new URL.

While content management system 606 is presented with specific components, it should be understood by one skilled in the art, that the architectural configuration of system 606 is simply one possible configuration and that other configurations with more or less components are also possible.

The system 700 can include a cache of high-speed memory connected directly with, in close proximity to, or integrated as part of the processor 710. The system 700 can copy data from the memory 715 and/or the storage device 730 to the cache 712 for quick access by the processor 710. In this way, the cache can provide a performance boost that avoids processor 710 delays while waiting for data. These and other modules can control or be configured to control the processor 710 to perform various actions. Other system memory 715 may be available for use as well. The memory 715 can include multiple different types of memory with different performance characteristics. The processor 710 can include any general purpose processor and a hardware module or software module, such as module 1 732, module 2 734, and module 3 736 stored in storage device 730, configured to control the processor 710 as well as a special-purpose processor where software instructions are incorporated into the actual processor design. The processor 710 may essentially be a completely self-contained computing system, containing multiple cores or processors, a bus, memory controller, cache, etc. A multi-core processor may be symmetric or asymmetric.

To enable user interaction with the computing device 700, an input device 745 can represent any number of input mechanisms, such as a microphone for speech, a touch-sensitive screen for gesture or graphical input, keyboard, mouse, motion input, speech and so forth. An output device 735 can also be one or more of a number of output mechanisms known to those of skill in the art. In some instances, multimodal systems can enable a user to provide multiple types of input to communicate with the computing device 700. The communications interface 740 can generally govern and manage the user input and system output. There is no restriction on operating on any particular hardware arrangement and therefore the basic features here may easily be substituted for improved hardware or firmware arrangements as they are developed.

Storage device 730 is a non-volatile memory and can be a hard disk or other types of computer readable media which can store data that are accessible by a computer, such as magnetic cassettes, flash memory cards, solid state memory devices, digital versatile disks, cartridges, random access memories (RAMs) 725, read only memory (ROM) 720, and hybrids thereof.

The storage device 730 can include software modules 732, 734, 736 for controlling the processor 710. Other hardware or software modules are contemplated. The storage device 730 can be connected to the system bus 705. In one aspect, a hardware module that performs a particular function can include the software component stored in a computer-readable medium in connection with the necessary hardware components, such as the processor 710, bus 705, display 735, and so forth, to carry out the function.

Computer system 750 is an example of computer hardware, software, and firmware that can be used to implement the disclosed technology. System 750 can include a processor 755, representative of any number of physically and/or logically distinct resources capable of executing software, firmware, and hardware configured to perform identified computations. Processor 755 can communicate with a chipset 760 that can control input to and output from processor 755. In this example, chipset 760 outputs information to output 765, such as a display, and can read and write information to storage device 770, which can include magnetic media, and solid state media, for example. Chipset 760 can also read data from and write data to RAM 775. A bridge 780 for interfacing with a variety of user interface components 785 can be provided for interfacing with chipset 760. Such user interface components 785 can include a keyboard, a microphone, touch detection and processing circuitry, a pointing device, such as a mouse, and so on. In general, inputs to system 750 can come from any of a variety of sources, machine generated and/or human generated.

Chipset 760 can also interface with one or more communication interfaces 790 that can have different physical interfaces. Such communication interfaces can include interfaces for wired and wireless local area networks, for broadband wireless networks, as well as personal area networks. Some applications of the methods for generating, displaying, and using the GUI disclosed herein can include receiving ordered datasets over the physical interface or be generated by the machine itself by processor 755 analyzing data stored in storage 770 or 775. Further, the machine can receive inputs from a user via user interface components 785 and execute appropriate functions, such as browsing functions by interpreting these inputs using processor 755.

It can be appreciated that exemplary systems 700 and 750 can have more than one processor 710 or be part of a group or cluster of computing devices networked together to provide greater processing capability.
